Transient simulation of flow over a throttle body

The project shows the flow of air in a throttle body at approximately 1atm pressure difference.

The throttle body moves as follows:

• From 0 to 2 ms the valve should rotate by 25 degrees.
• From 2 to 4ms it should stay at 25 degrees.
• After which by 8ms the valve should get back to its original position

First, we clean the given model of excessive geometry and cover the inlet and outlet areas with a surface for inflow and outflow boundaries. Also, we check the normals are facing the flow domain.
